BACKGROUND OF THE INVENTION

One major common problem faced by cellular and landline serviceproviders is market competition. In today's climate of competitivemarkets, cellular service providers have found that one way for them togrow market share and defend their businesses is to be proactive andform alliances, and to partner with landline service providers. Inaddition, cellular service providers seek to differentiate their serviceofferings, and to capture the largest portion of market revenue bymeeting an ever increasing demand for access to a wide range of mediaforms such as MP3 encoded audio, still and video imaging, data, instantmessaging, and email. In a similar manner, the landline serviceproviders have found that to grow market share and ward off competition,they too must be proactive and form alliances, and to partner withcellular service providers. Support for broad economical access to theseconverging forms of communication is needed to enable unfettered marketgrowth, and to support the development and use of new handheld devicesneeded to provide increasing levels of mobile multimedia communicationfunctionality.

Although the formation of alliances and partnerships between cellularservice providers and landline service providers may help to ward offcompetition, such alliances and partnerships are faced with otherproblems. For example, the erection of cellular infrastructure such ascellular towers may be an expensive venture since this may requireacquisition of real estate, whether in the form of outright purchases orthrough leasing. Cellular infrastructure also requires the establishmentof one or more expensive backbone links to handle core network traffic.Another cellular-related problem is that the cellular signals do notpenetrate and propagate in buildings such as homes and offices verywell. This is especially true with the frequencies that are typicallyutilized in the United States, which may vary between 800 MHz and 1900MHz or 1.9 GHz.

Present day communication networks and, in particular, wirelessnetworks, are subject to varying conditions that may cause temporarylosses of signal, and can ultimately lead to loss of a call. Some of theparticipants on the call may not receive all of the informationexchanged by the parties during the call due to poor communicationconditions. There are also times when portions of a call are ofimportance and one or more parties wish to have a record of the call.

Further limitations and disadvantages of conventional and traditionalapproaches will become apparent to one of skill in the art, throughcomparison of such systems with some aspects of the present invention asset forth in the remainder of the present application with reference tothe drawings.

DETAILED DESCRIPTION OF THE INVENTION

Certain embodiments of the present invention relate to communicationover a hybrid wired and wireless networks. More specifically, certainembodiments of the present invention relate to a method and system forcall handling through simulcasting of wireless network traffic for anactive subscriber from a wireless service provider servicing the activesubscriber to a broadband wired and/or a wireless LAN, and/or PAN usinga broadband access gateway.

An aspect of the present invention provides seamless merging of widearea networks (WANs), from any kind of wired and/or wireless wide areanetworks, to pockets of wired and/or wireless local area networks(WLANs) and personal area network (PANs), which may be located in homesor other environment such as an office or business. The merging of thesevarious types of networks enables transparent communication of all typesof media between access devices, which may be wired or wirelesslycoupled to one or more of these networks. Seamless communication may beprovided to access devices as they transition from one type of networkto another type of network.

FIG. 1 is a block diagram illustrating an architecture of an exemplarycommunications system in which a representative embodiment of thepresent invention may be practiced. Referring to FIG. 1, there is showna first location 102, a second location 104, a broadband access provider(BAP) 106, a public switched telephone network (PSTN) 108, a transportnetwork 110, wireless service provider networks including a CDMA network112 and a GSM/EDGE/GPRS network 114, and access devices 122, 124, 126,and 128. The first location 102 comprises a gateway 118 having a modem116, a wireless interface(s) block 120, and the access devices 122, 124.The access devices 122, 124, 126, 128 may comprise, for example, amobile multimedia handset having a high level of functionality such as,for example, that of one or more of a digital video or still camera, aportable audio (MP3) player, a personal digital assistant, and a voicehandset. The access devices 122, 124, 126, 128 may be capable ofoperating using, for example, a personal area network and/or wirelesslocal area network compliant with, for example, Bluetooth, IEEE802.11a/b/g/n, and/or IEEE 802.15.3a ultra-wideband standards. Thesecond location 104 comprises a router 130 having a modem 132, and aplurality of wireless access devices. The plurality of wireless accessdevices at the second location 104 may comprise a personal computer (PC)138, a laptop 136 and a wireless personal digital assistant (PDA) 134. Aperipheral such as a digital camera 142 may be coupled to the personalcomputer 138. Other peripherals such as printers, digital scanners,speakers, and the like, which are not shown, may also be coupled to thepersonal computer 138 and/or laptop 136. The wireless interface block120 may comprise a plurality of interfaces such as a Bluetoothinterface, an IEEE 802.15.3a ultra-wideband interface, and anycombination of an IEEE 802.11a, b, g and/or n interface.

FIG. 1 also comprises an “other broadband access provider” block 144, an“other cellular/PCS service provider” block 146, a central control andmanagement block 148, and content provider 150. The “other broadbandaccess provider block 144” may be, for example, a cable, DSL, or othertype of broadband access provider. The central control and managementblock 148 may comprise suitable logic, circuitry and/or code that may beadapted to handle content delivery and security functions such asauthentication, validation, key or certificate management, andauthorization. The central control and management block 148 may also beadapted to handle provisioning, service management, and accounting. In arepresentative embodiment of the present invention, the central controland management block 148 may establish communications links with, forexample, the gateway 118, the broadband access provider 106, the otherbroadband access provider 144, the other cellular/PCS service provider146, the CDMA network 112, and the GSM/EDGE/GPRS network 114 usingactual or virtual connections.

The broadband access provider 106 may be, for example, a cable operator,telephone company, or satellite operator providing Internet access alongwith other communication services. In instances where BAP 106 is atelephone company, broadband service to locations 102, 104 may beprovided via DSL or other broadband access technology. Accordingly, themodems 116, 132 may be DSL modems. In instances where BAP 106 is a cableoperator, broadband service to locations 102, 104 may be provided viacable. Accordingly, the modems 116, 132 may be DOCSIS compliant or othertype of cable modem. Given the rapid decrease in the cost of leasedtelephone lines over the past decade or more, the connection to thelocation 102, 104 may also be T1 or T3 connections. For example, aswitch located at a central office (CO) (not shown) may be utilized tocouple a T1 or T3 connection between the second location 104 and thePSTN 108.

The gateway 118 may comprise an integrated DSL modem, cable modem orother high-speed modem that may be required for handling a connectionsuch as a T1 or T3 connection. Alternatively, the gateway 118 may becoupled to an external DSL modem, cable modem or other high-speed modemthat may be capable of handling connections such as a T1 or a T3connection. The gateway 118 may be adapted so that it has access toprotocol stack information that may be related to the GSM and/or CDMAnetworks 114, 112, respectively. The gateway 118 may also be adapted toprovide protocol support for communication with “other cellular/PCSservice provider” block 146.

Each of the CDMA and GSM/EDGE/GPRS networks 112, 114 may comprise aplurality of cell sites (a/k/a cellular towers) that are located ingeographical cells within each of the networks. Within the GSM/EDGE/GPRSnetwork 114, each of the cell sites such as, for example, cell site 114a may comprise a base transceiver station (BTS), and one or more basetransceiver stations (BTSs) may be coupled to wireless carrier centraloffice 114 b. The wireless carrier central office 114 b may comprise abase station controller/radio network controller (BSC/RNC) such asBSC/RNC 114 d. One or more base station controllers/radio networkcontrollers (BSCs/RNCs) may be coupled to the core network 114 e, thatcomprises a network edge switch called a mobile switching center (MSC),such as MSC 114 g, and a serving GPRS support node (SGSN)/packet dataserving node (PDSN) 114 f, of the GSM/EDGE/GPRS network 114. The mobileswitching center may be coupled to, for example, the PSTN 108 via thetransport network 110. As an access device moves out of range of a firstcell site to within range of a second cell site, the decrease signalpower received from the first cell site and the increase in signal powerreceived from the second cell site causes initiation of handoff of acall from the first cell site to the second cell site. In cases wherethere is no second cell site to handoff to, the call may be maintainedby the first cell site power until it is attenuated to a threshold whereit is no longer feasible to maintain the call. At the point where thepower reaches or falls below this threshold, the call may drop and anyrelated call resources may be relinquished. In a home and/or officeenvironment, it may be desirable to have a second network to which thecall may be handed off to.

As an illustration, a user may be on their way home and as the userapproaches their home, the signal may fall below a minimum signal powerthreshold that is required to maintain a call. However, instead ofdropping the call, the call may be handed off to, for example, a PAN ora wireless local area network (WLAN) that may be located within theuser's home or an unlicensed wireless access system that may be locatedin the user's home. For example, with reference to FIG. 1, as accessdevice 126 migrates from the vicinity of the serving cell site 114 a inGSM/EDGE/GPRS network 114 towards the wireless interface 120 in thefirst location 102, the call may be handed off from the cell site 114 aof the GSM/EDGE/GPRS network 114 to the wireless interface 120 coupledto the gateway (GW) 118 at the first location 102. Accordingly, insteadof the call being dropped, the call has been seamlessly handed off andis now being handled by the gateway 118 via the wireless interface 120.The resulting wireless data may then be communicated to theGSM/EDGE/GPRS network 114 via the broadband connection to the BAP 106which is connected to the broadband wireless local area networkcontroller (BWC) 114 c.

In a representative embodiment of the present invention, voice and datatraffic related to an existing active wireless call or connection for asubscriber may be routed from a serving wireless service provider suchas, for example, the GSM/EDGE/GPRS network 114 to a broadband wiredand/or a wireless WAN, LAN, and/or PAN using a broadband access gatewaysuch as, for example, the gateway 118, so as to provide seamlesshandoff. The broadband wired and/or a wireless LAN (WLAN), and/or PANusing the broadband access gateway may be located in a home, forexample. Simulcasting is the simultaneous broadcasting of the sameinformation over two different communication paths or channels.Accordingly, in a representative embodiment of the present invention,voice and data related traffic may be simulcasted to an access deviceand to the home broadband access gateway upon initiation of a call, inaddition to receipt of a call from a calling party. In the former casewhere a calling party places a call to a called party, related voice anddata for the called party and/or the calling party may be communicatedto the broadband access gateway 118. When the calling party is at home,the calling party may use their access device or some other accessdevice that is now serviced by the broadband access gateway 118 forfurther communication.

With reference to FIG. 1, the access device 126 that may be, forexample, a mobile multimedia handset, may initiate a call destined forthe access device 128 that may also be, for example, such as a mobilemultimedia handset. Once the call is setup and established, the mobileaccess device 126 may be serviced by a cell site such as, for example,the cell site 114 a located in the GSM/EDGE/GPRS network 114, while themobile access device 128 may be serviced by a cell site such as, forexample, the cell site 112 a located in the CDMA network 112. Whilecommunication is active between the mobile access devices 126 and 128,the mobile access device 126 may enter a region in which the receptionis poor and as a result, the user of the mobile access device 126 mayhave a desire to record the call so that it may be subsequentlyreplayed.

In one representative embodiment of the present invention, a soft orhard button may be utilized to activate recording of the conversationbetween users of the mobile access devices 126 and 128. The wirelesscarrier central office 114 b and/or the mobile wireless carrier centraloffice may be adapted to detect when the signal level has fallen below aspecified threshold and thereby cause the soft button for recording tobe displayed on the mobile access device. The wireless carrier centraloffice 114 b may also be adapted to determine whether there issufficient bandwidth and available space to handle recording of the callat the broadband access gateway 118. In another representativeembodiment of the present invention, the recording of the call may bestored at a location other than the broadband access gateway 118 suchas, for example, another access device in communication with thebroadband access gateway 118. If the wireless carrier central office 114b determines that there is insufficient bandwidth and/or memory forstoring the recorded conversation, then the wireless carrier centraloffice 114 b may send an indication to the mobile access device 126,that initiated the recording. In the case where there is a hard buttonavailable, the hard button may be depressed or otherwise enabled inorder to activate remote recording at the broadband access gateway 118.

The hard or soft button may also be utilized to terminate remoterecording of an existing call between the mobile access devices 126 and128. In this regard, the hard or soft button may be depressed in orderto terminate recording of an existing call.

There may be instances where a user of the mobile access device 126desires to record only a portion of an existing call. For example,during an existing call where the user of mobile access device 126 isthe calling party, the called party may want to give the calling party atelephone number and/or address. Immediately prior to receiving thetelephone number and/or address, the calling party may activate orinitiate remote recording of the conversation at the first location 102via the broadband access gateway 118 by depressing the soft or hard keyon the mobile access device 126. Once the called party has completeddisclosing the telephone number and/or address, the calling party maydeactivate recording by depressing the soft or hard key on the mobileaccess device 126. Once the mobile access device 126 is within operatingrange of the broadband access gateway 118, for example, when the user ofmobile access device 126 is at the first location 102, the user may playback the recording on the mobile access device 126, or on another accessdevice such as, for example, a personal computer coupled to thebroadband access gateway 118.

A user may be on a conference call with a plurality of other wirelessand wired users and may choose to store a portion of the conference callat the broadband access gateway 118, while at the same time attending toan urgent second call. In this regard, the conference call may still beactive and being recorded while the user tends to another call. Aftercompleting the urgent second call, the user may switch back to theteleconference and may continue to record the conference call at thebroadband access gateway 118, or terminate recording of the conferencecall using the soft or hard button.

In another representative embodiment of the present invention, wheneverrecorded media is stored at broadband access gateway such as, forexample, the broadband access gateway 118 of FIG. 1, a notification ofthe stored recorded media may be presented on a mobile access devicesuch as, for example, the mobile access device 126. Hence, a specialpop-up menu showing an identifier of one or more stored media may beautomatically displayed on the called mobile access device 126 wheneverthe mobile access device 126 is within an operating range of the gateway118. The popup menu may comprise playback keys that may be utilized toplay back the recording and may include, for example, play, forward,rewind and stop.

The GSM/EDGE/GPRS network 214 orthe mobile access device 224, for example, may determine that the mobileaccess device 224 being served is associated with a broadband accessgateway capable of call recording. The GSM/EDGE/GPRS network 214 ormobile access device 224, for example, may then cause the mobile accessdevice 224 to present a display such as the display 300 to the user ofthe mobile access device 224. In a representative embodiment of thepresent invention, the call recording icon 320 and the call recordbutton 340 may not appear if the mobile access device 224 has noassociated broadband access gateway. Association of an access devicesuch as, for example, the mobile access device 224, and a broadbandaccess gateway such as, for example, the broadband access gateway 218 ofFIG. 2 may be detected by a wide area network using identificationinformation provided by or available from the mobile access device 224.This identification information may be provided, for example, when theaccess device enters, or while within the coverage area of the wide areanetwork. The identification information may comprise, for example,access device identifiers, network addresses, media access control (MAC)addresses, electronic serial numbers, personal identification numbers(PINs) of users, and digital certificates.

In a representative embodiment of the present invention, the wirelesscarrier central office 214 b of FIG. 2 may be adapted to determinewhether there is sufficient bandwidth and available space to handlerecording of the call at the broadband access gateway 218. If thewireless carrier central office 214 b determines that there isinsufficient bandwidth and/or memory for storing the recordedconversation, then the wireless carrier central office 214 b may send anindication to the mobile access device 226, that initiated therecording.

FIG. 4 illustrates a display 400 showing an exemplary error messagescreen 422 that may be displayed by an access device that maycorrespond, for example, to the mobile access device 224 of FIG. 2, inaccordance with a representative embodiment of the present invention.The display 400 of FIG. 4 comprises a network indicator 410, a networkservices indicator area 412, a battery life indicator, a time of dayindicator, and a day and date indicator. The network services indicatorarea 412 of FIG. 4 comprises an Internet protocol (IP) phone serviceicon 415, a printer service icon 416, a stereo entertainment icon 417, apay music service icon 418, a video entertainment icon 419, and a callrecording icon 420 showing those services that may be advertised by abroadband access gateway such as, for example, the gateway 218 of FIG.2, as being available to an appropriately identified or authorized userof the access device.

A representative embodiment of the present invention may displayinformation such as that presented in FIG. 4 on an access device suchas, for example, one of the mobile access devices 224, 226, 228 of FIG.2 following an attempt to activate call recording following the examplegiven above with respect to FIG. 3. The mobile access device 224, forexample, may display information such as the text 430 informing the userof the mobile access device 224 that the call cannot be recorded, andthe text 432 explaining that no storage for the recording of the call isavailable. Other situations may also arise that prohibit the recordingof call information including, for example, the lack of bandwidth in thepath from the wireless carrier central office 214 b of FIG. 2 to thebroadband access gateway 218, a failure to establish communicationbetween the wireless carrier central office 214 b and the broadbandaccess gateway 218, the fact that the broadband access gateway 218 iscurrently busy, to name only a few.

In an representative embodiment of the present invention, the wirelesscarrier central office 214 b and/or the mobile access device 226 may beadapted to detect when the signal level has fallen below a specifiedthreshold and thereby cause a soft button for recording to be displayedon the mobile access device 226. In the case where there is a hardbutton available, the hard button may be depressed or otherwise enabledin order to activate remote recording at the broadband access gateway218. The hard or soft button may also be utilized to terminate remoterecording of an existing call between the mobile access devices 226 and228. In this regard, the hard or soft button may be depressed in orderto terminate recording of an existing call.

FIG. 5 illustrates a display 500 showing an exemplary warning messagescreen 522 that may be displayed by an access device that maycorrespond, for example, to the mobile access device 224 of FIG. 2, inaccordance with a representative embodiment of the present invention.The display 500 of FIG. 5 comprises a network indicator 510, a networkservices indicator area 512, a battery life indicator, a time of dayindicator, and a day and date indicator. The network services indicatorarea 512 of FIG. 5 comprises an Internet protocol (IP) phone serviceicon 515, a printer service icon 516, a stereo entertainment icon 517, apay music service icon 518, a video entertainment icon 519, and a callrecording icon 520 showing those services that may be advertised by abroadband access gateway such as, for example, the gateway 218 of FIG.2, as being available to an appropriately identified or authorized userof the access device.

An access device such as, for example, the mobile access device 224 ofFIG. 2, that may comprise, for example, a mobile multimedia handset maydisplay information like that presented in FIG. 5, while being served bya wide area network such as, for example the GSM/EDGE/GPRS network 214of FIG. 2. In the illustration of FIG. 5, the state of the networkindicator 510 represents a low signal strength condition that may causea call to be lost. Other conditions of a communication link such as, forexample, interference and noise may also affect the viability of a call.In a representative embodiment of the present invention, one or both ofa wide area network such as, for example, the wireless carrier centraloffice 214 b of the GSM/EDGE/GPRS network 214, and an access device suchas, for example, the mobile access device 224, may determine that poorsignal quality may result in loss of the call. As previously described,an access device such as mobile access device 224, for example, may beassociated with a broadband access gateway, and as a result, the mobileaccess device 224 may display an icon such as the call recording icon520 of FIG. 5, indicating that call recording is available.

In a representative embodiment of the present invention, a user of anaccess device may be notified when conditions exist that may result inloss of a call, and if available may be offered the option of recordingthe call for later playback. In such a situation, the user of the accessdevice may be presented with a visual indication such as the warningmessage screen 522, permitting the user to enable the recording of thecall by the associated broadband access gateway. In the example of FIG.5, the user may be presented with a brief statement of the callsituation such as, for example, the text 530, and may be permitted toenable call recording by clicking on or selecting, for example, a recordbutton 540. In another representative embodiment of the presentinvention, call recording may be enabled by the user for all calls, orfor only those calls that meet certain conditions such as, for example,call impairment (e.g., as above), calls to or from certain parties,calls at certain times of the day, to name only a few examples.Notification to other parties on the call that recording is taking placemay be provided. Once call recording is active, the user of the accessdevice for which recording was initiated may be presented with otheroptions and information such as, for example, the duration of thecurrent recording, and a button (not shown) enabling the user of theaccess device to halt recording. Should the associated broadband accessgateway exhaust available call storage, or should other difficultiesarise, the user may be notified that call recording cannot continue. Insuch a situation, call recording may be automatically de-activated.

In a representative embodiment of the present invention, there may beinstances where a user of an access device such as, for example, themobile access device 224 of FIG. 2 (e.g., a mobile telephone) desires torecord only a portion of an existing call. For example, during anexisting call where the user of, for example, the mobile access device224 is the calling party, the called party may want to give the callingparty a telephone number and/or address Immediately prior to receivingthe telephone number and/or address, the calling party may activate orinitiate remote recording of the conversation at the first location 202via the associated broadband access gateway 218 by depressing a soft orhard key on the mobile access device 224 such as, for example, the callrecord button 340 of FIG. 3. Once the called party has completeddisclosing the telephone number and/or address, the calling party maydeactivate recording by depressing a similar or the same soft or hardkey on the mobile access device 224. Once the mobile access device 224is within operating range of the wireless interface 220 of theassociated broadband access gateway 218, for example, (i.e., when theuser of mobile access device 224 is at the first location 202), the usermay play back the recording on the mobile access device 224. In variousrepresentative embodiments of the present invention, the user may alsochoose to use another access device such as, for example, a personalcomputer coupled to the broadband access gateway 218, or an accessdevice capable of accessing the broadband access gateway 218 using, forexample, the broadband connection supported by the modem 216 of FIG. 2.In such an arrangement, the user of the mobile access device 224 mayplayu back the recording while being served by the a wide area networkaccessible via the broadband connection supported by modem 216. This mayenable a user of the mobile access devices 222, 224, 226, 228 to accessrecordings while in the coverage areas of the GSM/EDGE/GPRS network 214and the CDMA network 212.

FIG. 6 illustrates a display 600 showing an exemplary recorded callsscreen 622 that may be displayed by an access device that may correspondto, for example, the mobile access device 224 of FIG. 2, in accordancewith a representative embodiment of the present invention.

In the illustration of FIG. 6, the network indicator 610of the display 600 is shown in a form representing communication with apersonal area network (PAN) or wireless local area network (WLAN) of abroadband access gateway such as, for example, that supported by thewireless interface 220 of the gateway 218, shown in FIG. 2.

The recorded calls screen 622 shown in FIG. 6 also comprises recordedcall entries 630, 632, 634 representing three calls recorded by a userof an access device such as, for example, the mobile access device 224of FIG. 2. The recorded call entries 630, 632, 634 of FIG. 6 eachcontain information indicating whether the recorded call is an incomingor outgoing call, the date and time of the call, the calling or callednumber, and the length of the recording. The user of the mobile accessdevice 224 may, for example, select from one of the listed calls, or mayexit the recorded calls screen 622 by selecting the EXIT button 640.Although described with reference to an access device such as, forexample, a mobile multimedia handset, the information shown in FIG. 6may also be presented via other access devices (e.g., wireless personaldigital assistants, personal computers, and the like) and using otherforms of user interface (e.g., a graphical rather than textualinterface), without departing from the spirit and scope of the presentinvention.

FIG. 7 is a message exchange or “ping-pong” diagram 700 illustratingexemplary messaging during a call by a user of an access device such as,for example, the mobile access devices 222, 224, 226, 228 of FIG. 2being served via a wide area network such as, for example, theGSM/EDGE/GPRS network 214 of FIG. 2, during which call recording by anassociated broadband access gateway is enabled by the user, inaccordance with a representative embodiment of the present invention. Inthe illustration of FIG. 7, the three vertical lines represent a widearea network 702, an access device 704, and a broadband access gateway706 that may correspond, for example, to the GSM/EDGE/GPRS network 214,the mobile access device 224, and the broadband access gateway 218,respectively, of FIG. 2. The horizontal lines represent message trafficor groups of messages exchanged between a source and a destination, thedestination being indicated by the arrow head. The vertical dimensionrepresents time, advancing downward on the message exchange diagram 700.

In a representative embodiment of the present invention, an accessdevice 704 may initiate or receive a call via the wide area network 702using messaging 710, 712. The messaging 710, 712 may comprise multiplemessages for establishing a wireless call on the wide area network 702.In the illustration of FIG. 7, the wide area network 702 may activate apath to transport multimedia information (e.g., voice signals) 714between the wide area network 702 and the access device 704. At somepoint during the call, the user of the access device 704 may desire torecord the call, and may cause a call recording request message 716 tobe sent to the wide area network 702. Although depicted in FIG. 7 as arequest from the access device 704, in another representative embodimentof the present invention, the recording request message 716 may alsooriginate from within the wide area network 702 when, for example, it isdetected that the call may be lost. The wide area network 702 may thensend an acknowledgement message 718 to the access device 704, and mayalso send a record start message 720 to the broadband access gatewayassociated with the access device 704. The association of the accessdevice 704 and the broadband access gateway 706 may be establishedearlier in the call, for example, when identification information isprovided by the access device 704 to the wide area network 702(messaging not shown), as described above. Upon receiving the recordstart message 720, the broadband access gateway 706 may send anacknowledgement message 722, and may enable recording of callinformation for the call from the wide area network 702. Upon receipt ofthe acknowledgement message 722, the wide area network may beginsimulcasting the multimedia information (e.g., voice signals) 714 of thecall to the broadband access gateway 706 via a second path as multimediainformation (e.g., voice signals) 714 a, which is then stored by thebroadband access gateway 706.

At yet a later point in time, the user of the access device 704 maychoose to end recording of the call, and may cause a recording haltrequest message 726 to be sent to the wide area network 702. The widearea network 702 may respond with an acknowledgement message 728, andmay transmit a stop call recording message 730 to the associatedbroadband access gateway 706. The broadband access gateway 706 may sendan acknowledgement message 732 to the wide area network 702, and maythen cease call recording 733 by terminating the storage of multimediainformation (e.g., voice signals) for the call. Upon receiving theacknowledgement message 732, the wide area network may ceasesimulcasting the multimedia information (e.g., voice signals) 714 a, andmay maintain the path carrying multimedia information (e.g., voicesignals) 714 between the wide area network 702 and the access device704. The call may continue, for example, until the user of the accessdevice 704 causes a call terminate message 736 to be sent to the widearea network 702. The wide area network 702 may then respond with anacknowledgement message 738, ending the call.

In a representative embodiment of the present invention, the accessdevice 704 may later enter into wireless or wired communication with thebroadband access gateway 706, and may send a call playback message 740requesting multimedia information (e.g., voice signals) for the callthat was recorded earlier. The broadband access gateway 706 may send anacknowledgement message 742, and may arrange playback of the requestedcall 743. The broadband access gateway 706 may then activate a path andsend multimedia information (e.g., voice signals) 744 to the accessdevice 704. The access device may later send a stop playback message746, ending playback of the recorded call, and the broadband accessgateway 706 may respond with an acknowledgement message 748.

FIG. 8 is a flowchart 800 of an exemplary method supporting handling ofcalls through simulcasting of multimedia information, in accordance witha representative embodiment of the present invention. The followingdiscussion makes references to the elements of FIG. 2. The method ofFIG. 8 begins with an access device such as, for example, the mobileaccess device 224 in an idle state (i.e., not engaged in a call) (block810). A call initiated or received by the mobile access device 224 isthen established via a wide area network such as, for example, theGSM/EDGE/GPRS network 214 (block 812). The mobile access device 224 maycomprise, for example, a mobile multimedia handset, a wireless personaldigital assistant, or other similar device. During the establishment ofthe call, the wide area network 214 or the mobile access device 224, forexample, may determine whether the mobile access device 224 isassociated with a broadband access gateway such as, for example, thegateway 218 (block 814). This determination may, for example, useidentification information contained within the mobile access device224. Such identification information may comprise, for example, anelectronic serial number, an Internet protocol (IP) address, a digitalcertificate, or other information that may identify a broadband accessgateway associated with the mobile access device 224.

If the access device is not associated with a broadband access gateway,the method of FIG. 8 ends (block 834). If, however, it is determinedthat the mobile access device 224 has an associated broadband accessgateway, the mobile access device 224 may notify the user that callrecording is available (block 816). This notification may take the formof the call recording icon 320 shown in the illustration of FIG. 3, forexample. At some point during the call, the user of the mobile accessdevice 224 may desire to record the information being exchanged. Inanother representative embodiment of the present invention, the widearea network call may experience difficulties, and the user may benotified of the potential loss of the call with a screen such as, forexample, the illustration of FIG. 5. For any of a number of reasons, theuser may choose to activate recording of information exchanged duringthe call. The information to be recorded may comprise multimediainformation such as, for example, streaming video, broadcast video,digitized voice, data, digitized video, still images, or other forms ofdigital media. Based upon a user activation of call recording, thebroadband access gateway 218 may receive, via the broadband network, arequest that call recording be activated (block 818). Upon receiving therequest, the broadband access gateway 218 may determine whether storageis available for call recording (block 820), and may notify the user ofthe mobile access device 224 if there is a lack of storage formultimedia information for the call (block 822), in a manner such asthat shown in FIG. 4, for example. In another representative embodimentof the present invention, a determination may be made whether sufficientnetwork bandwidth is available to support recording of the multimediainformation for the call. If a lack of storage or a lack of bandwidthexists, the method of FIG. 8 then ends (block 834).

If, however, storage is available for the recording of the call (block820), the gateway may send to the access device, via the broadband andwide area networks, an acceptance of the request to record themultimedia information for the call (block 824). The gateway 218 maythen begin receiving, via the broadband network, a stream of multimediainformation for the call carried by the wide area network (block 826).The broadband access gateway 218 may then store the received multimediainformation for the call (block 828). The broadband access gateway 218may, for example, comprise the necessary call storage such as, forexample, the storage 219 of FIG. 2, or may store the multimediainformation for the call using external storage such as, for example,the storage 213 accessible via the Internet 206.

At a later point in the wide area network call, the user of the mobileaccess device 224 may choose to end call recording, and may cause thebroadband access gateway 218 to receive a request to halt recording ofthe multimedia information for the call (block 830). The stream ofmultimedia information received from the wide area network via thebroadband network then ceases. In another representative embodiment ofthe present invention, the request to halt recording may be initiated,automatically, when storage for the call information is exhausted, orbandwidth for transport of call information is no longer available.Following recording of the call, the broadband access gateway may notifythe user of the mobile access device 224 of the availability of therecorded call information (block 832) in a manner such as thatillustrated in FIG. 6, for example. The method of FIG. 8 then ends(block 834).

It should be noted that although the previous discussion makes referenceto functions performed by a wireless carrier central office, othernetwork elements may perform those functions in other arrangements inaccordance with a representative embodiment of the present invention.For example, in an intelligent network (IN) environment, an applicationsprocessor (AP) or other suitable network entity may perform tasks thatare described above as being performed by an wireless carrier centraloffice, without departing from the spirit or scope of the presentinvention. It should also be noted that although the previous discussionfocuses primarily on the capabilities and actions of the broadbandaccess gateways 118, 218 of FIGS. 1 and 2, respectively, the samecapabilities and actions may also apply to the router 130 of FIG. 1.

Other elements of such anetwork may, for example, include computer peripherals such as digitalscanners, digital cameras, printers, headphones, and pointing devices,that may be located within the immediate proximity of a person. A PANmay be an ad-hoc network of such communication devices. In arepresentative embodiment of the present invention, access deviceswithin the PAN may communicate with other access devices within the PANand also with other access devices that are located in other networksaccessible via the PAN. The personal area networks may include datanetworks such as, for example, a Bluetooth compliant network, andInstitute of Electrical and Electronics Engineer (IEEE) 802.15.3acompliant wireless networks. Such personal area networks may operate inunlicensed radio frequency spectrum such as, for example, the 2.4 and 5gigahertz regions. Details of one example of a personal area network areprovided in the document “Bluetooth Core Specification V1.2”, Nov. 5,2003, from Bluetooth SIG, Inc., the complete subject matter of which ishereby incorporated herein by reference, in its entirety. For example,in a Bluetooth® wireless PAN, a first Bluetooth®-enabled wireless accessdevice may communicate with a second Bluetooth®-enabled wireless accessdevice within the PAN. Additionally, either of the first and secondBluetooth®-enabled wireless access devices may communicate with theInternet or another LAN or WAN via the Bluetooth® wireless PAN.

In a representative embodiment of the present invention, a gateway maybe adapted to provide seamless and transparent communication between aplurality of access devices and a plurality of networks. Thefunctionality of the gateway may be divided, for example, intoapplication content functionality, and configuration and managementfunctionality. The application content functionality may, for example,deal with the types of applications that may be supported by the gatewayas well as the various types of data that may be received, processedand/or transmitted by the gateway. In this regard, application contentfunctionality may also include the manner in which other devices and/orsystems may utilize data from the gateway.

Content and application services are important because all theinformation coming into and leaving the home from either the WAN side(i.e., the broadband connection side), or from the PAN side (i.e., theaccess device side) converges at the gateway. The PAN side may compriseBluetooth, wireless LAN (IEEE 802.11a/b/g/n), IEEE 802.15.3aultra-wideband, or cellular, for example. Notwithstanding, the gatewaymay be adapted to convert, for example, wirelessly receivedGSM-formatted information into, for example, Internet protocol(IP)-formatted information and in reverse, converts IP-formattedinformation into wireless GSM-formatted information suitable forover-the-air transmission. Support for other wireless communicationprotocols such as TDMA, CDMA, and UMTS may also be provided. In arepresentative embodiment of the present invention, the gateway maycomprise suitable circuitry, logic and/or code that may be adapted toreceive and process MPEG related data, which may be suitable for displayon a screen. The gateway in an embodiment of the present inventionfunctions as a focal point where data converges from a plurality ofwired and wireless services. Although, in a particular embodiment of thepresent invention the gateway may do very little in terms of actualcontent aggregation, there is virtual aggregation of data. The convergeddata may be integrated and or otherwise utilized to offer uniqueopportunities for launching various content and application servicesfrom a single strategic location. Since the gateway in an embodiment ofthe present invention is the focal point where data converges, one ormore protocol stacks may be employed for launching the various contentand application services.

The gateway in a representative embodiment of the present invention maybe adapted to route calls based on established rules that may beprogrammed into the gateway. For example, the gateway may be governed bya rule which states that local calls are to be routed to an incumbentlocal exchange carrier (iLEC), while long distance calls are to behandled by Long Distance Carrier Company. Accordingly, when a calloriginates at the gateway and it is determined that the call is a localcall, the gateway may be adapted to route the call to the iLEC. However,if the gateway determines that the call is a long distance call, thenthe gateway may be adapted to route the call to Long Distance CarrierCompany.

A representative embodiment of the present invention may leverageexisting broadband infrastructure that is commonly found in many homesand businesses today. Because a consumer is already paying for the useof the broadband infrastructure in their home or office, leveraging theuse of the existing broadband infrastructure for communication with widearea networks results in minimal or no communication costs. Thebroadband infrastructure may be, for example, a cable or DSLinfrastructure.

The wireless interface function provided by the gateway located within ahome, for example, may be utilized to route or communicate a great dealof traffic to a wired network such as a broadband network or a wirelessnetwork such as a GSM or CDMA network via a broadband connection. Inother words, the wireless gateway infrastructure provided by arepresentative embodiment of the present invention provides a scalablenetwork infrastructure that rides on an existing access infrastructurealready supplied by a broadband service provider to a home, office orbusiness. Additionally, the scalable infrastructure provided by thegateway also solves the problems associated with signal penetration andpropagation, thereby providing improved quality of service (QoS). From amarket perspective, a wireless service provider may now have access tothe necessary infrastructure to provide improved wireless services tousers within a home or office. Accordingly, in order to rapidly increasetheir growth, wireless service providers may now target that portion ofthe in-home landline or plain old telephone system (POTS) business,which have traditionally been handled by incumbent local exchangecarriers (ILECs) or other LECs.

The unlicensed mobile access gateway described above may possess asignificant amount of processing power. The gateways of existing systemsfall short of realizing the full potential of the merged wired andwireless communication network that is enabled by a representativeembodiment of the present invention. Numerous basic and enhancedcommunication services may be enabled or provided by the gateway.Support for access devices such as, for example, mobile multimediahandsets and PDAs may be involved in order to utilize these basic andenhanced communication services enabled by the new wave of digitaltechnologies. Current and/or proposed mobile access gateway systems,however, do not provide the range of support needed for their use by theeveryday consumer.

Accordingly, the present invention may be realized in hardware,software, or a combination of hardware and software. The presentinvention may be realized in a centralized fashion in at least onecomputer system, or in a distributed fashion where different elementsare spread across several interconnected computer systems. Any kind ofcomputer system or other apparatus adapted for carrying out the methodsdescribed herein is suited. A typical combination of hardware andsoftware may be a general-purpose computer system with a computerprogram that, when being loaded and executed, controls the computersystem such that it carries out the methods described herein.

The present invention may also be embedded in a computer programproduct, which comprises all the features enabling the implementation ofthe methods described herein, and which when loaded in a computer systemis able to carry out these methods.
